GM applies for LT5, LTX trademarks... are new small block variants coming?

Recently discovered General Motors trademark applications for LT4, LT5, LT88 and LTX have observers wondering what kind of high-performance offerings could be on their way. A new LT4 would mark a return of the engine designation first used on the Corvette Grand Sport, SLP Pontiac Firehawk and SLP Chevrolet Camaro SS from 1996 and 1997. Supposition at Corvette Forum - which provided advance intel on the C7 like these leaked images - believes a new LT4 could go into the high-performance trim of the next-gen, 2015 Camaro that would be more powerful than the 580-horsepower Camaro ZL1.
Seeing an LT5 again would also be déjà vu - in its former life it was a 5.7-liter V8 for the C4 Corvette ZR-1 from 1990-1994 designed by Lotus, producing from 370 hp to 405 hp. A mix of rumor and hope is that the new LT5 will be a supercharged evolution of the 6.2-liter LT1 (pictured) placed in the new C7 Corvette, and that it will go into the C7 version of the ZR1 pumping out something like 700 hp.
The LTX trademark is, as with that last letter, a complete mystery. If the "X" isn't a generic way to denote the whole LT family, it's wondered if it LTX could refer to a crate motor offering like the LSX.

Ford Mustang Shelby GT350R named Road & Track Performance Car of the Year

With a 526-horsepower, 5.2-liter V8 that roars to 8,250 rpm, it's really hard to consider the 2016 Ford Shelby Mustang GT350R an underdog in any fight. However, the Shelby held the lowest as-tested price and was only middle of the pack in terms of power in Road & Track's 2016 Performance Car of the Year challenge. The 'Stang's numbers clearly didn't tell the whole story about the potent coupe because Ford's muscle car grabbed the title in this year's test. A model needs to be new or significantly updated to be eligible for the honor, and R&T found an impressive slate of eight candidates this year. The challengers included the Bentley Continental GT3-R, Cadillac ATS-V Coupe, Chevrolet Corvette Z06, Dodge Viper ACR, Mercedes-AMG GT S, and Porsche Cayman GT4. The Ferrari 488 GTB was the most expensive of the bunch with an as-tested price of $347,942, which is five times more than the Shelby. Once the group was together, R&T hustled them over curving roads and on the National Corvette Museum Motorsports Park. There was a lot to love about the Shelby, even in this impressive crew. "With a flat-plane crank and Sport Cup 2 tires, the GT350R is a Mustang turned up to 11," editor-in-chief Larry Webster said in the announcement of the results. The GT350R joins some great company. Past winners include the Porsche 911 GT3 last year and the Corvette in 2013.

Why does the Corvette Stingray have so many vents? Here's why

Just looking at the new 2014 Chevrolet Corvette Stingray, it's not hard to see that the car's design was created with aerodynamics at the forefront, but Chevrolet designers point out exactly what went into designing the iconic coupe in a pair of recently released videos. The videos show the Corvette going through early design phases, including clay models and wind tunnel tests, as well as talking to the car's chief engineer, Tadge Juechter.
Both videos help explain various aspects of the C7 Corvette, but it's the aero tuning of the car that is most interesting. This includes extra attention paid to the lower air dam and vented hood to help reduce drag and lift, while the rear quarter inlets are for differential and transmission cooling. Juechter said that some of these aero-tuned elements were inspired from GM's involvement in racing.
